Encourage others when fault is found at every turn, especially those from 3rd world countries. Throughout the ages there have always been folks who "strain out a gnat and swallow a camel". The gnat being the smallest "unclean" creature and the camel the largest. I'm very familiar with the failing of not viewing matters through the lense of grace. All that can be done when folks stumble and criticize over some point is forgive them, release them and move on.
Remember the miller’s donkey.
The miller, son and donkey went to the market. The miller rode the donkey all the way and people exclaimed, “Cruel man, riding himself and making his son walk.” So he got down and his son rode; the people said, “What a lazy son for riding while poor old father walks.” Then both father and son rode, and people said, “Cruelty to animals, poor donkey.” So they got down and carried the donkey on a pole, but folks said, “Here are two donkey slang’s carrying another donkey slang” Then all three walked and people said, “What fools to have a donkey and not ride it.”
So lets go ahead with our work for God and not care what folks think or say.
